Answer:
- Oxiding agent - sulphuric acid (3H2SO4)
- Reducing agent - aluminium (Al)
Explanation:
Oxiding agent act as "Reduction" which loses oxygen in the product side.
Reducing agent act as "Oxidation" which gains oxygen.
Answer:
it's a chemical change
Explanation:
When two different chemical substances are mixed they are no longer the same and can not be changed back so therefore it's a Chemical reaction.
Answer: The answer is B. Hope this helps :)
Explanation:
Answer:
Solution
dT = K * b
K (H2O) = 1.86 0C
b(C2H6O2) = dT/ K = 33.2 / 1.86 = 17.85(mol/kg)
b(C2H6O2)= n (C2H6O2) / m (H2O)
m (H2O) = V * = 12.2 * 1 = 12.2 (kg)
n (C2H6O2) = b (C2H6O2) * m (H2O) = 17.85 * 12.2 = 217.77 (mol)
n (C2H6O2) = m / M;
m (C2H6O2) = n * M = 217.77 * (12*2 + 1*6 + 16 *2) = 13501.74 (g) = 13.5 (kg)
V (C2H6O2) = m / = 13.5 / 1.11 = 12.16 (L)
Answer V (C2H6O2) = 12.16 L
